If one end of the frustum CDGL (Fig. 17. ) be 90 feet square, the other end 60 feet square, and the height RN 36 feet; what is the height of the whole pyramid VCD: and what are the solidity and lateral surface of the frustum DPDN--GR45--3015. And, GPRN-36. Then, 15: 36: : 45: 108VN, the height of the whole pyramid. And, 108--3672VR, the height of the part VLG. The solidity of the large pyramid is 291600 (Art. 48. ) of the small pyramid 86400 of the frustum CDGL 2(15200 The lateral surface of the large pyramid is 21060 (Art. 49. ) of the small pyramid 9360 of the frustum 11700 PROBLEM VII. To find the Solidity of a Wedge. 54. Add The Length Of The Edge To Twice The Length Of The Base, And Multiply The Sum Bv J Of The Product Of The Height Of The Wedge And The Breadth Of The Base. Let LAB the length of the base. (Fig. 20. ) GH the length of the edge. 6 BC the breadth of the base. APG the height of the wedge. Then, L--lAB--GHAM. If the length of the base and the edge be equal, as BM and GH, (Fig. 20. ) the wedge MBHG is half a parallelopiped of the same base and height. And the solidity (Art. 43. ) is equal to half the product of the height, into the length and breadth of the base; that is to I bhl. If the length of the base be greater than that of the edge, as ABGH; let a section be made by the plane GMN, parallel to HBC. This will divide the whole wedge into two parts MBHG and AMG. The latter is a pyramid, whose solidity (Art. 48. ) is iMx(L--I) The solidity of the parts together, is, therefore, i bhll bh x(L--)-bh3l6A2L--bh 2libhx(2Ll) If the length of the base be less than that of the edge, it is evident that the pyramid. . .

If the base of a right prism be a regular hexagon whose sides are each 2 feet 3 inches, and if the height be 16 feet, what is the lateral surface Ans. 216 square feet. If the areas of the two ends be added to the lateral surface, the sum will be the whole surface of the prism. And the superficies of any solid bounded by planes, is evidently equal to the areas of all its sides. Ex. 2. If the base of a prism be an equilateral triangle whose perimeter is 6 feet, and if the height be 17 feet, what is the surface 1 The area of the triangle is 1.732. (Art. 11.) And the whole surface is 105.464. PROBLEM III. To find the Solidity of a Pyramid. 48. Multiply The Area Of The Base Into i Of The Height. The solidity of a prism is equal to the product of the area of the base into the height. (Art. 43.) And a pyramid is i of a prism of the same base and altitude. (Sup. Euc. 15, 3. Cor. 1.) Therefore the solidity of a pyramid whether right or oblique, is equal to the product of the base into A of the perpendicular height. Ex. 1. What is the solidity of a triangular pyramid, whose height is 60, and each side of whose base is 41 The area of the base is 6.928 And the solidity is 138.56. 2. Let ABC (Fig. 16.) be one side of an oblique pyramid whose base is 6 feet square; let BC be 20 feet, and make an angle of 70 degrees with the plane of the base; and let CP be perpendicular to this plane. What is the.solidity of the pyramid? 3. What is the lateral surface of a regular pyramid whose axis is 12 feet, and whose base is 18 feet square? Ans. 540 square feet. The lateral surface of an oblique pyramid may be found, by taking the sum of the areas of the unequal triangles which form it. Bookseller Inventory # APC9781130343021

Ex. If the slant-height of a frustum of a regular octagonal pyramid be 42 feet, the sides of one end 5 feet each, and the sides of the other end 3 feet each; what is the lateral surface?, Ans. 1344 square feet. 52. If the slant-height be not given, it may be obtained from the perpendicular height, and the dimensions of the two ends. Let GD (Fig. 17.) be the slant-height of the frustum CDGL, RN or GP the perpendicular height, ND and RG the radii of the circles inscribed in the perimeters of the two ends. Then PD is the difference of the two radii: And the slant-height GD = x/(GP3+YD3). Ex. If the perpendicular height of a frustum of a regular hexagonal pyramid be 24, the sides of one end 13 each, and the sides of the other end 8 each; what is the whole surface? t/(BC-BP)=CP, (Fig.7.)thati8, .v/(l33-633)=11.258 And V 83--43 e= 6.928 The difference of the two radii is, therefore, 4.33 The slant-height =V(243 + 4.333)=24.3875 The lateral surface te 1536.4 And the whole surface, 2141.75. 53. The height of the whole pyramid may be calculated from the dimensions of the frustum. Let VN (Fig. 17.) be the height of the pyramid, RN or GP the height of the frustum, ND and RG the radii of the circles inscribed in the perimeters of the ends of the frustum. Then, in the similar triangles GPD and VND, DP: GP:: DN: VN. The height of the frustum subtracted from VN, gives VR the height of the small pyramid VLG. The solidity and lateral surface of the frustum may then be found, by subtracting from the whole pyramid, the part which is above the cut ting plane. This method may serve to .

A SOLID IS SAID TO BE REGULAR, WHEN ALL ITS SOLID ANGLES ARE EQUAL, AND ALL ITS SIDES ARE EQUAL AND REGULAR POLYGONS. The following figures are of this description; 1. The Tetraedron, 2. The Hexaedron or cube, 3. The Octaedron, 4. The Dodecaedron, 5. The Icosaedron, whose sides are four triangles; six squares; eight triangles; twelve pentagons; twenty triangles. Besides these five, there can be no other regular solids. The only plane figures which can form such solids, are triangles, squares, and pentagons. For the plane angles which contain any solid angle, are together. less than four right angles or 360. (Sup. Euc. 21,2.) And the least number which can form a solid angle is three. (Sup. Euc.

A SOLID IS SAID TO BE REGULAR, WHEN ALL ITS SOLID ANGLES ARE EQUAL, AND ALL ITS SIDES ARE EQUAL AND REGULAR POLYGONS. The following figures are of this description; 1. The Tetraedron, 2. The Hexaedron or cube, 3. The Octaedron, 4. The Dodecaedron, 5. The Icosaedron, whose sides are four triangles; six squares; eight triangles; twelve pentagons; twenty triangles. Besides these five, there can be no other regular solids. The only plane figures which can form such solids, are triangles, squares, and pentagons. For the plane angles which contain any solid angle, are together. less than four right angles or 360. (Sup. Euc. 21,2.) And the least number which can form a solid angle is three. (Sup. Euc. Def. 8, 2.) If they are angles of equilateral triangles, each is 60. The sum of three of them is 180, of . Bookseller Inventory # APC9781231205310

If the base of a right prism be a regular hexagon whose sides are each 2 feet 3 inches, and if the height be 16 feet, what is the lateral surface Ans. 216 square feet. If the areas of the two ends be added to the lateral surface, the sum will be the whole surface of the prism. And the superficies of any solid bounded by planes, is evidently equal to the areas of all its sides. Ex. 2. If the base of a prism be an equilateral triangle whose perimeter is 6 feet, and if the height be 17 feet, what is the surface 1 The area of the triangle is 1.732. (Art. 11.) And the whole surface is 105.464. PROBLEM III. To find the Solidity of a Pyramid. 48. Multiply The Area Of The Base Into i Of The Height. The solidity of a prism is equal to the product of the area of the base into the height. (Art. 43.) And a pyramid is i of a prism of the same base and altitude. (Sup. Euc. 15, 3. Cor. 1.) Therefore the solidity of a pyramid whether right or oblique, is equal to the product of the base into A of the perpendicular height. Ex. 1. What is the solidity of a triangular pyramid, whose height is 60, and each side of whose base is 41 The area of the base is 6.928 And the solidity is 138.56. 2. Let ABC (Fig. 16.) be one side of an oblique pyramid whose base is 6 feet square; let BC be 20 feet, and make an angle of 70 degrees with the plane of the base; and let CP be perpendicular to this plane. What is the.solidity of the pyramid? 3. What is the lateral surface of a regular pyramid whose axis is 12 feet, and whose base is 18 feet square? Ans. 540 square feet. The lateral surface of an oblique pyramid may be found, by taking the sum of the areas of the unequal triangles which form it. Bookseller Inventory # APC9781130343021

Ex. If the slant-height of a frustum of a regular octagonal pyramid be 42 feet, the sides of one end 5 feet each, and the sides of the other end 3 feet each; what is the lateral surface?, Ans. 1344 square feet. 52. If the slant-height be not given, it may be obtained from the perpendicular height, and the dimensions of the two ends. Let GD (Fig. 17.) be the slant-height of the frustum CDGL, RN or GP the perpendicular height, ND and RG the radii of the circles inscribed in the perimeters of the two ends. Then PD is the difference of the two radii: And the slant-height GD = x/(GP3+YD3). Ex. If the perpendicular height of a frustum of a regular hexagonal pyramid be 24, the sides of one end 13 each, and the sides of the other end 8 each; what is the whole surface? t/(BC-BP)=CP, (Fig.7.)thati8, .v/(l33-633)=11.258 And V 83--43 e= 6.928 The difference of the two radii is, therefore, 4.33 The slant-height =V(243 + 4.333)=24.3875 The lateral surface te 1536.4 And the whole surface, 2141.75. 53. The height of the whole pyramid may be calculated from the dimensions of the frustum. Let VN (Fig. 17.) be the height of the pyramid, RN or GP the height of the frustum, ND and RG the radii of the circles inscribed in the perimeters of the ends of the frustum. Then, in the similar triangles GPD and VND, DP: GP:: DN: VN. The height of the frustum subtracted from VN, gives VR the height of the small pyramid VLG. The solidity and lateral surface of the frustum may then be found, by subtracting from the whole pyramid, the part which is above the cut ting plane. This method may serve to .
